在Python中将日期时间转换为序数失败 [英] Convert datetime to ordinal in python fails

问题描述

我曾与日期合作。我想将日期时间转换为序数，但脚本失败。

i been had worked with dates. I want to convert datetimes to ordinal but my script fails.

from datetime import datetime

date = "2016/12/07 17:45"
date_strip = datetime.strptime(date, '%Y/%m/%d %H:%M').date()
ordinal = date_strip.toordinal()
# ordinal = 736305
normal_date = datetime.fromordinal(ordinal)
# normal_date = 2016-12-07 00:00:00 not 2016-12-07 17:45:00

怎么了？他们可以帮我吗？

whats wrong? ca they help me please?

推荐答案

因为 ordinal 仅存储日期。该序数不能包含时间：

Because ordinal stores just the date. the ordinal cannot contain the time:

该日期的公历格里高里序数，其中第一年的1月1日具有序数1。对于任何日期对象d，date.fromordinal（d.toordinal（））== d。

the proleptic Gregorian ordinal of the date, where January 1 of year 1 has ordinal 1. For any date object d, date.fromordinal(d.toordinal()) == d.

如果要转换为时间戳或从时间戳转换常见问题，请尝试如此回答。

If you want to convert to/from timestamps instead of ordinals, try this so answer.
